RASN is dedicated to providing the most up to date and trusted information. [1], During inflammation, arginine amino acid residues can be enzymatically converted into citrulline residues in proteins such as vimentin, by a process called citrullination. Atlanta: American College of Rheumatology; c2020. Information is shared for educational purposes only. What Happens If CCP Antibody Is Positive? Anti-MCV titers are distributed more homogenously (from low to very high titers) and are better suited than anti-CCP to measure disease activity.

Often, a patient with rheumatoid arthritis and positive anti-CCP test result is called having seropositive rheumatoid arthritis. This process may well be the cause of the inflammatory process since citrullinated proteins and the enzymes responsible for producing them are found in inmflamed synovium. Hey there.
